Mastercard introduced a stablecoin risk product at Money20/20 USA in Las Vegas. The tool is called Stablecoin Security.
It attaches a stablecoin risk score to a payment before any funds move on-chain, combining payment data with blockchain data. The score flags fraud, scams, sanctions exposure and other financial crime indicators.
Borderless.xyz and Keyrails are the named launch partners. The product reaches North America first, with commercial availability expected worldwide in 2027, Mastercard said.
What Stablecoin Security checks before a payment completes
The product analyzes four inputs: transaction context, the origin of funds, exposure to restricted parties, and scam indicators. It returns a stablecoin risk score before the payment completes.
Mastercard is shipping it as a platform-agnostic API. Institutions route calls into existing fraud, compliance and case management workflows instead of standing up a separate risk operating model.
The company positions it alongside Crypto Credential and Crypto Secure, its earlier digital asset controls, and says it extends existing fraud capabilities rather than replacing them.
“Stablecoins are creating new possibilities for value exchange.”
Ann Johnson, executive vice president of Security Solutions at Mastercard, in the company’s announcement

The partners Mastercard named, and the one joining in 2027
Borderless.xyz gives institutions one connection to licensed stablecoin providers and routes payments between them. Its network covers more than 113 countries and 72 currencies.
Keyrails handles high-value cross-border trade settlement, weighted toward emerging markets. Both firms came through Mastercard’s Start Path Blockchain and Digital Assets program.
The first launch partners are infrastructure firms, not banks
Neither named launch partner is a bank. Both already sit inside the payment infrastructure the product is designed to monitor.
That places the first stablecoin risk checks with firms moving the money, rather than with the institutions holding deposits.
Mastercard says it will expand the product’s reach and adoption in 2027, including through BVNK. It acquired the stablecoin infrastructure company in August 2026.
Why BIS research says a transfer is not always a payment
The commercial case rests on research Mastercard cites rather than produces. The source is BIS Working Paper 1359, published 11 June 2026.
Fabian Schär, Anneke Kosse, Tara Rice, Takeshi Shirakami and Jirapat Siridhasanakul examined 593 million event logs from 141 million Ethereum transactions in 2025, covering USDT, USDC and PYUSD.
Their finding is that a transfer is often one leg of something larger. Roughly a third of stablecoin transactions emit multiple event logs, and some run past 1,000 steps.
The paper’s second finding complicates the product
The authors also conclude the three stablecoins are not used interchangeably. Each carries a different mix of trading, lending, arbitrage, liquidity provision and settlement activity.
That matters for any stablecoin risk model, because token behavior is not uniform. A model may need to account for those differences rather than treating the asset as irrelevant.
Key numbers behind stablecoin risk scoring
- BIS analyzed 593 million transfer event logs across 141 million Ethereum transactions in 2025 (BIS Working Paper 1359, June 11, 2026)
- About one third of stablecoin transactions produce multiple event logs rather than a single transfer (BIS Working Paper 1359, June 11, 2026)
- Nearly 60% of all transfer events sit inside those complex transactions, which misclassifies almost six in ten if each is counted as a payment (BIS Working Paper 1359, June 11, 2026)
- Borderless.xyz connects institutions across more than 113 countries and 72 currencies (Mastercard, October 19, 2026
- Worldwide commercial availability is expected in 2027, with North America first and no date given (Mastercard, October 19, 2026)
Mastercard owns the rails and sells the controls
Mastercard already runs its own stablecoin settlement platform and owns the infrastructure beneath it through BVNK. Stablecoin risk scoring is the third layer in that stack.
Competitors are filling adjacent slots. Visa moved stablecoin prefunding into commercial use on Visa Direct. Euronet and Fireblocks opened stablecoin-funded card issuing to banks and fintechs.
Settlement is becoming table stakes across the networks. Compliance is becoming the billable layer on top of it.

The gap between the announcement and a live service
Mastercard has not published a North American availability date. The company said the product reaches the region first, without saying when, so 2027 is the only stated worldwide availability timeframe.
The announcement was timed to Money20/20, where Mastercard scheduled sessions on stablecoin security and agentic commerce across three days.
What to watch on stablecoin risk pricing
Whether banks pay for this is the open question. A separate BIS working paper finds stablecoin demand responds to bank deposit pricing, a reminder that bank behavior can shape the size of the addressable market.
Whether banks buy a stablecoin risk layer from Mastercard is a separate question, and one the company has not addressed.
Watch also whether agentic payments inherit these controls, because AI agent payment rails face the same settlement finality problem that stablecoin risk scoring addresses.
